How do I parse TOON in Zig?

serde.toon.fromSliceManaged(Directory, allocator, input) from serde.zig.

How is TOON told apart from YAML?

By its array headers such as items[2]:. A TOON document without one reads the same as YAML, so either format gives the same struct.

TOON to Zig struct

Paste a TOON document. zigshape decodes it with the reference implementation and writes Zig structs that serde.zig reads with serde.toon.

API responseSmallest int widths from observed range; auto enum suggestion; missing/null become optional.

Upload

users[3]{id,name,role,active}:
  1,Alice,admin,true
  2,Bob,editor,false
  3,Carol,viewer,true
page: 1

Directory.zig

const serde = @import("serde");

pub const Directory = struct {
    users: []const User,
    page: u8,
};

pub const User = struct {
    id: u8,
    name: []const u8,
    role: []const u8,
    active: bool,
};

Field decisions

Why each field got its type. Click a row to see it in the input; edit to override.

struct Directory $ 2 fields

struct User $.users[*] 4 fields

How TOON maps to Zig

Tabular arrays like users[3]{id,name}: become a slice of a generated struct.
Inline arrays like tags[2]: a,b become slices of scalars.
Indented objects become nested structs, as with YAML.
